Moreover, the cost reduction is official
AMD has brought down the cost of Ryzen 7000 processors in China.
If the Ryzen 9 7900 previously cost $430 in China, the new price is $370. The Ryzen 7 7700 has dropped to $285, the Ryzen 5 7600 has dropped to $210.
Usually CPUs in China (not only AMD, but also Intel) are more expensive than in the US, but after this price cut, CPUs are now cheaper in China. For comparison, Ryzen 9 7900 in the US (from retailer Microcenter) can be purchased for $400, Ryzen 7 7700 for $320, Ryzen 5 7600 for $220.
